It had no XDR because it was "reader makes it
right" and datatypes
were tagged.
That's the first I've heard of that and I really like it. Most of the
time, you are on a network of machines that are the same, so why have
a network byte order, reader makes it right will just work. Neat.
I guess I don't quite understand that. I can get how it works for simple
data types (integers, floating point numbers, perhaps strings) but it seems
like it breaks
It was only for native types

-- struct, array, pointers, etc -- have rules. See the link if you care
for nitty-gritty details.
